3 / 12 page 3 2005 Semtech Corp. www.semtech.com SC1566 POWER MANAGEMENT Notes: (1) Low duty cycle pulse testing with Kelvin connections required. (2) Defined as the input to output differential at which the output voltage drops to 1% below the value measured at a differential of 0.7V. (3) Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this requirement. Adjustable versions only. (4) Guaranteed by design. (5) When V ADJ exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error amplifier and connects V ADJ instead. r e t e m a r a Pl o b m y Ss n o i t i d n o C t s e Tn i Mp y Tx a Ms t i n U ) . t n o C ( O V e g a tl o V t u o p o r D ) 2 ( ) 1 ( I O A 5 . 1 =0 0 20 0 3V m 0 0 4 I O A 3 =0 5 30 5 4V m 0 0 6 t n e r r u C d a o L m u m i n i M ) 3 ( I O V N I V = O V 7 . 0 +1 0 1 A µ ti m i L t n e r r u CI L C 0 . 3 5 . 4 5 . 6 A J D A e g a tl o V e c n e r e f e R ) 1 ( V F E R V N I V , V 2 . 2 = J D A V = T U O I , O A m 0 1 =8 8 1 . 10 0 2 . 12 1 2 . 1V 6 7 1 . 14 2 2 . 1 t n e r r u C n i P t s u j d A ) 4 ( I J D A V J D A V = F E R 0 1 0 0 2 A n d l o h s e r h T n i P t s u j d A ) 5 ( V ) J D A ( H T 0 1 . 0 0 2 . 0 0 4 . 0 V N E t n e r r u C n i P e l b a n EI N E V N E V , V 0 = N I V 3 . 3 =5 . 1 0 1 A µ d l o h s e r h T n i P e l b a n EV H I V N I V 3 . 3 = 8 . 1 V V L I V N I V 3 . 3 = 4 . 0 n o i t c e t o r P e r u t a r e p m e T r e v O l e v e l p ir T h g i HT I H 5 7 1C ° s i s e r e t s y HT T S Y H 0 1C ° Electrical Characteristics (Cont.) Unless specified: V EN = VIN. Adjustable Option (VADJ > VTH(ADJ)): VIN = 2.2V to 5.5V and IO = 10µA to 3A. Fixed Options (V ADJ = GND): VIN = (VO + 0.7V) to 5.5V and IO = 0A to 3A.
